The juridification of sport: A comparative analysis of children’s rugby and cricket in England and South Africa

This article takes as its point of departure the notion of juridification in sport and, in particular, the perspective that the term has previously often been used in sport and law literature in a too narrow and limiting sense. Using the work of Ken Foster as a platform, the article examines a more nuanced notion of juridification. It does this by first unpacking two levels of juridification – the more well-known notion of increased legal intervention is considered before moving on to a more sophisticated application of the idea in terms of its impact upon rules and practices in sport. Foster termed this juridification as domestication. The article then applies these ideas in a practical context by examining two applications of the two children’s sports (rugby and cricket) in England and South Africa. The article concludes as to the future developments that are likely to occur. Despite the economic and cultural differences it seems likely that South Africa will continue to follow England, as is the case with the first level of juridification, and that the rules and their enforcement will themselves become more domesticated. It is likely that coaches and educators will find themselves under increased pressure to conform from both a general fear of litigation and a changing internal regulatory regime of sport codes

Delivering mental healthcare to patients with a depressive disorder alongside a life-limiting illness

The concurrent assessment and treatment of mental health disorders and palliative illnesses is complex. Affective disorders are more prevalent in people who need palliative care. Identifying the most suitable place of care and multi-professional multidisciplinary teams to provide support can be challenging and bewildering for professionals and patients. Mental health clinicians may be left with a sense of therapeutic nihilism, while palliative care teams can feel limited by the mental health resources available for treating those living with significant physical and mental health needs. We discuss the fictional case of a gentleman with metastatic bowel cancer who has developed symptoms of depressive disorder and identify how taking a pragmatic patient-centred approach can offer a route through potential dilemmas when seeking to provide individualised care based on needs. We used lay person experience alongside our own experiences of novel mechanisms for cross-specialty working in order to direct psychiatric trainees' approaches to such cases

Drug therapies for attentional disorders alter the signal-to-noise ratio in the superior colliculus

Despite high levels of use, the mechanism of action of effective pharmacotherapies in attention deficit hyperactivity disorder (ADHD) is unknown. It has recently been hypothesized that one site of therapeutic action is the midbrain superior colliculus, a structure traditionally associated with visual processing, but also strongly implicated in distractibility, a core symptom of ADHD. We used male juvenile Wistar rats to examine the effects of therapeutically relevant doses of methylphenidate and d-amphetamine on collicular activity in vitro. Here we report a novel shared mechanism of the two drugs whereby they enhance the signal-to-noise ratio in the superior colliculus. The effects on the signal-to-noise ratio were mediated by serotonin (5-HT) via a pre-synaptic mechanism. This modulatory action would bias the system towards salient events and lead to an overall decrease in distractibility

Mechanism of action of 5-arninosalicylic acid

5-Aminosalicylic Acid (5-ASA) has been used for over 50 years in the treatment of inflammatory bowel disease in the pro-drug form sulphasalazine (SASP). SASP is also used to treat rheumatoid arthritis. However whether the therapeutic properties of SASP are due to the intact molecule, the 5-ASA or sulphapyridine components is unknown. Several mechanisms of action have been proposed for 5-ASA and SASP including interference in the metabolism of arachidonic acid to prostaglandins and leukotrienes, scavenging,of reactive oxygen species, effects on leucocyte function and production of cytokines. However, it is unlikely that the anti-inflammatory properties of SASP and 5-ASA are due to several different properties but more likely that a single property of 5-ASA explains the theraapeutic effects of 5-ASA and SASP. Reactive oxygen species (ROS) are involved in the metabolism of prostaglandins and leukotrienes and can act as second messengers, and so the scavenging of ROS may be the single mechanism of action of 5-ASA that gives rise to its antiinflammatory effects in both inflammatory bowel disease and rheumatoid arthritis

Sexually dimorphic expression of secreted frizzled-related (SFRP) genes in the developing mouse Mullerian duct

In developing male embryos, the female reproductive tract primordia (Müllerian ducts) regress due to the production of testicular anti-Müllerian hormone (AMH). Because of the association between secreted frizzled-related proteins (SFRPs) and apoptosis, their reported developmental expression patterns and the role of WNT signaling in female reproductive tract development, we examined expression of Sfrp2 and Sfrp5 during development of the Müllerian duct in male (XY) and female (XX) mouse embryos. We show that expression of both Sfrp2 and Sfrp5 is dynamic and sexually dimorphic. In addition, the male-specific expression observed for both genes prior to the onset of regression is absent in mutant male embryos that fail to undergo Müllerian duct regression. We identified ENU-induced point mutations in Sfrp5 and Sfrp2 that are predicted to severely disrupt the function of these genes. Male embryos and adults homozygous for these mutations, both individually and in combination, are viable and apparently fertile with no overt abnormalities of reproductive tract development

Crustal Deformation and Fault Strength of the Sulawesi Subduction Zone

This paper investigates the seismicity and rheology of the North-Sulawesi subduction zone. Body-wave modeling is used to estimate focal mechanisms and centroid depths of moderate magnitude (M5–M6.5) earthquakes on the North Sulawesi megathrust and surrounding region. The slip vectors of megathrust earthquakes radiate outward from Sulawesi, indicating motion that is incompatible with the relative motion of two rigid plates. Instead, the observed deformation implies lateral spreading of high topography, controlled by gravitational potential energy contrasts. This finding suggests that the observed deformation of Sulawesi results from stresses transmitted through the lithosphere, rather than basal tractions due to circulation in the mantle. Our modeling of the force balance on the megathrust shows that the subduction megathrust is weak, with an average shear stress of ∼13 MPa and an effective coefficient of friction of 0.03. Elsewhere in Sulawesi, slip vectors of other earthquakes suggest similar potential-energy-driven deformation is present, but at significantly slower rates. Our results show the importance of lateral rheology contrasts in determining deformation rate, and hence seismic hazard, in response to a given driving force.Newton Institutional Links Leverhulme Fellowshi
